VirtualLab Fusion Toolboxes

The toolboxes in VirtualLab offer a scalable set of technologies for solving your optical design task based on a common easy-to-learn user interface. The combination of several toolboxes in VirtualLab enables the solution of multidisciplinary optical design tasks. The following toolboxes are available:

If needed, it is possible to add customizable capabilities to your system by means of a powerful programming interface.

Starter Toolbox

All in one – from ray tracing to physical optics

With the Starter Toolbox, you can benefit immediately from VirtualLab’s innovative concept of unified optical design. The Starter Toolbox enables you to optimize laser, imaging and illumination systems. You can choose from a wide range of light sources: mono- and multimode, cw and pulsed lasers, excimer lasers, LEDs, VCSELs and thermal sources. This toolbox offers great flexibility in the definition of optical components with refractive, diffractive, freeform and hybrid surfaces. Effects like polarization, interference, diffraction and coherence are taken into account for the evaluation of a large variety of merit functions. [more]

Grating Toolbox

Rigorous analysis of gratings in optical systems

Grating structures are widely used in optical systems. The Grating Toolbox contains a variety of instruments to help you carry out end-to-end modelling of such systems. The Grating Toolbox provides rigorous modelling techniques for electromagnetic analysis of 2D and 3D surface and volume gratings and of periodic structures in general. The powerful grating analyzer and other tools compute the diffraction efficiency, near and far fields and fields inside gratings. Effects like conical diffraction, polarization and dispersion are included. Using the Grating Toolbox alongside other toolboxes enables you to analyze gratings and diffractive structures in laser, imaging and illumination systems. [more]

Diffractive Optics Toolbox

Design of diffractive components made easy

User-friendly session editors guide you through the design workflows – from system setup to exporting fabrication data. The Diffractive Optics Toolbox allows you to design diffractive and refractive optical elements. Applications include laser beam splitting and shaping as well as diffusing and homogenization of coherent and partially coherent light. The powerful Iterative Fourier Transform Algorithm, local and global parametric optimization tools are available. The designed surface profiles can be exported in several formats including STL and GDSII. A tolerance analysis for fabrication and alignment errors is available and most powerful when used together with the Starter Toolbox. [more]

Lighting Toolbox

Innovative design concepts for compact illumination systems

The Lighting Toolbox provides design tools for the shaping and homogenization of monochromatic and white LED light. The Lighting Toolbox enables you to design refractive and diffractive optical components for the shaping of LED light taking into account diffraction and interference as well as spatial and temporal partial coherence effects. Even higher flexibility can be achieved when cell arrays are used together with refractive elements for collimating the incident LED light. For the designed components, fabrication data can be exported in several formats including STL and GDSII. A tolerance analysis is also available and becomes most powerful when used together with the Starter Toolbox. [more]

Laser Resonator Toolbox

Eigenmode analysis, design and tolerancing of optical cavities

The Laser Resonator Toolbox allows you to analyze stable and unstable resonators including the calculation of fundamental modes, higher order modes and eigenvalues. The Laser Resonator Toolbox makes use of the full infrastructure of VirtualLab, including catalogs and all modeling engines. This allows you to set up even complex cavities very easily. Resonators may contain components such as mirrors, refractive and diffractive optical surfaces, index-modulated media and laser crystals. Together with the Starter Toolbox, ring resonators can also be considered, and effects like nonlinear gain, thermal lensing and stress-induced birefringence are included. [more]
